6. Types of Cotton hyb seed
Produced
Conventional Hand Emasculation & Pollination
Non Conventional ( Male Sterility based)
7. Conventional Method of
Production
Site Selection
Isolation distance – 30 mt between crop ,
5 mt between parents
Fertilizer Dose – 100:50:50 NPK per ha
Sowing of parents
Synchronization
Staggered planting
Plant Protection measures
8. Conventional Method of
Production
Emasculation of Female parents-
Generally done after 1 PM in the day
Crossing of Parents – Crossing work
generally starts after 1 week of flower
initiation. The pollination is done on the
next day between 8 AM to 11 Am can be
extended upto 1 PM .
Fertilization – It is done after 12-30 hours
of pollination,so crossed bud should be
kept in covered condition till 3-4 days.
9. Conventional Method of
Production
What makes the Hyb seed production
successful ?
Qualified Technical staff
Proper trained Labour
One person can emasculate & pollinate
about 250-400 flowers/day ( FAO standard)
10. Conventional Method of
Production
Picking is done for only the completely
opened boles.
Damaged,underdeveloped bolls should be
separated and removed before sorting.
11. Factors that may affect in
production ….
The planting ratio of male & female
No of flowers used in pollination from one female
flower
Stagerred showing patterns of the parents(proper
synchronization)
Stage & period of crossing
Vigour of female parents
Pollen production ability of the male parents
Position of boll set in the plant
12. Bt cotton or Transgenic Cotton
Bt gene is effective against Helicoverpa
armigera
Bt Direct tests gives the bt level at
moleculat level
Bt Quant (ELISA) tests gives the bt
quantity level
